Taliban say US must meet troop withdrawal deadline
Biden on Wednesday cast doubt on meeting the deadline, saying he was in the process of deciding when troops would leave.
"The Americans should end their occupation in accordance with the Doha deal and fully withdraw their forces from Afghanistan by May 1," Taliban spokesman Zabihullah Mujahid told AFP.
"If they don't do it, be it for any reason and pretexts, then they will be responsible for the consequences," he said, adding that "the people of Afghanistan will make their decision".
The deal, which excluded the Afghan government, saw the Taliban pledge in return to hold peace talks with the administration of President Ashraf Ghani.
The talks however have made little progress since starting in September, while violence -- which Washington has blamed on the Taliban -- has surged.
